본 연구는 간호대학생의 표준주의 지식과 표준주의 수행과의 관계에서 주관적 규범의 매개효과 를 규명하기 위해 시행되었다. 연구의 대상자는 J도에 소재한 3개 대학교의 임상실습을 완료한 4학년 간호 학과 재학생 195명이다. 수집된 자료로 SPSS 25.0 프로그램을 이용하여 t-test, ANOVA, Pearson's correlation 및 multiple regression을 실시하였다. 연구결과, 주관적 규범은 표준주의 지식과 표준주의 수행 사이에서 부분매개효과를 나타냈고, 표준주의 수행을 설명하는 설명력(R²)은 35%이었다. 따라서 간호대 학생의 표준주의 수행을 촉진하기 위해서는 표준주의 지식 함양 및 이를 통해 주관적 규범을 유도할 수 있 는 효과적 전략 마련이 필요하다.

Subjective knowledge (SK thereafter) is defined as what consumers think they know, or their perceived level of knowledge (Brucks, 1985). SK influences what consumers search for, the effort that they put into searching, and the purchasing decision and choice of brands they finally make (Hadar, Sood, & Fox, 2013; Moorman, Diehl, Brinberg, & Kidwell, 2004). The existing literature on consumer knowledge development mainly argues that SK development is associated with consumers’ product related experience, such as product ownership and experience from usage (Alba & Hutchinson, 2000; Park, Mothersbaugh, & Feick, 1994). This study contributes to the literature as follows. We consider a broad market segmentation where the market consists of product owners and non-owners, The literature suggests that these two groups of consumers should have different levels of perceived knowledge due to their different product-specific experience (Park et al., 1994). Our research specifically contends that it is important to distinguish, within the group of non-owners, between those who intend to buy and those who do not intend to buy the product. Thus, this study examines how previous ownership and intention to buy, which is the goal motivation, influence the SK levels of consumers, which in turn impacts on consumers’ heterogeneous preferences for different attributes within a product category. It is contended that the motivation to learn about a product category of non-car owners who have strong intentions to buy influences what this group learns compared to those non-owners who do not intend to buy. More specifically, the research proposes to uncover how learning influences how different groups of consumers perceive their subjective knowledge and how this relationship in turn shapes their preferences, especially when we compare owners and non-owners who have strong intentions of buying a product. Therefore, we develop following research hypotheses: H1: The SK level is positively associated with the product ownership experience. H2: The SK level is positively associated with purchase intention. H3: The relationship between purchase intention and SK level is moderated by the ownership of the product. H4: Preference heterogeneity for different types of brand attributes of the product between owners and non-owners is moderated by the SK level. The empirical context that illustrates the importance of this research is the Chinese car market where the majority of consumers are first time buyers. Our research shows that the SK level is positively associated with both car ownership and purchase intention. Furthermore, the segmentation analysis finds that purchase intention has a significant effect only on non-car owners’ SK level, while the effect on car owners’ SK level is insignificant. An interesting finding is that SK development, in turn, influences consumer’s preferences for different types of brand attributes of a product. We demonstrate the role of SK in forming consumer preference heterogeneity by comparing preferences for a tangible and a non-tangible brand attribute respectively across different consumer segments. We further show how this preference heterogeneity across two consumer segments (car owners versus non-car owners) depends on their SK level. The results of this study can be generalized beyond the specific context of the empirical study of the Chinese car market when marketers are considering new products launch or launching products where the majority of consumers may be unfamiliar with the product.

This study aims to prepare a solution necessary for boosting the consumption of environment-friendly agricultural products, positively reflecting consumers’ opinions that expect supplies of safe agricultural products to secure the domestic farms producing environment-friendly agricultural products and at the same time, to meet consumers’ needs. As a result of the hypothesis testing, of the subjective knowledge in Hypothesis 1, product knowledge had an impact on attitude, while purchase knowledge and use knowledge after purchase were not significant. Of the subjective knowledge in Hypothesis 2, purchase knowledge and product knowledge had significant impacts on purchase intention. Brand image in Hypothesis 3 had a significant impact on attitude, while brand image in Hypothesis 4 had a significant impact on purchase intention. As a result of the mediated regression analysis of Hypothesis 5, all of the subjective knowledge, purchase knowledge, product knowledge and use knowledge after purchase had an impact on purchase intention, partially mediated by attitude, and brand image, too, had an impact on purchase intention, partially mediated by attitude.
